UNT Biology 1710 Practice Exam 3|52 Questions with Verified Answers An excellent example of the genetic phenomenon known as continuous variation would be: a. flower color in plants. b. height in humans. c. human blood groups. d. epistasis. e. fur color in arctic animals - CORRECT ANSWER B) height in humans A human genetic trait passed from one generation to the next has an unusual inheritance pattern. The genotype and phenotype of the offspring depends only upon the genotype of the mo...

RNAS-C Exam 4 Practice Test 75 Questions with Verified Answers A couple expecting their second child is worried about Rh incompatibility. Their first child was Rh+. They have their blood typed. Which result would be cause for alarm? A) both parents Rh- B) both parents Rh+ C) man Rh- and woman Rh+ D) man Rh+ and woman Rh- - CORRECT ANSWER D) man Rh+ and woman Rh- Research indicates that allergies may actually be due to a mutation in the gene that encodes a skin protein called __________...

Fill in the gaps: single-celled yeasts reproduce by ____ and bacteria reproduce by ____. - ️️Single-celled yeast reproduce by budding and bacteria reproduce by binary fission. Define clones. - ️️Genetically identical organisms or cells. Define vegetative propagation. - ️️Reproduction from vegetative parts of a plant - usually an over-wintering organ. The artificial production of natural clones for use in horticulture and agriculture. (reproduction that does not take place thr...

***Make a flow chart to show how you would calculate the affect of a factor on bacterial growth using serial dilutions and agar plating - ️️set up series of cultures identical in every way EXCEPT for factor you are investigating e.g., temperature, presence of a nutrient or antibiotic etc>culture for several days>for each culture carry out a serial dilution>plate each dilution, making streaks on agar plate with sterile inoculating loop and label carefully to show which original cult...

What are clones? - ️️Genetically identical copies of an organism What is a clone? - ️️Genes, cells or whole organisms that carry identical genetic material because they are derived from the same original DNA (Genetically identical organisms) What are examples of clones? - ️️Identical twins (when zygote splits) Plant producing runners (asexual reproduction) Binary Fission in bacteria Mitosis (cells) What are the advantages of natural cloning? - ️️- Quick - allows organisms...

Compare the advantages and disadvantages of batch and continuous culture - ️️Growth rate: Batch has lag, log then stationary phase. Continuous has optimum rate maintained. Ease of set up and maintenance: Batch is easy to set up and run. Continuous is not easy, requires sophisticated equipment and constant monitoring and adjustment. Consequence of contamination: Batch has less chance. Loss of product must sterilise and start again. Continuous has more chance and is more costly to restart as...

a mutation made wild bananas parthenocarpic, what does this mean? - ️️they produce fruit without fertile seeds, which made them good to eat but also made them sterile. define what a clone is - ️️genetically identical organisms to both the parent organism and to each other. describe the characteristics of a wild banana - ️️1. full of hard seeds and virtually inedible does the frequency at which identical twins occur vary between species ? - ️️yes - in domestic cattle identical...

What are clones? - ️️Genetically identical copies. The term can apply to cells or whole organisms. How are clones produced? - ️️By asexual reproduction in which the nucleus is divided by mitosis. Mitosis creates two identical copies of DNA, which are then separated into two genetically identical nuclei before the cell divides to form two genetically identical cells. These cells may not be physiclly or chemically identical as, after division, they may differentiateto form two d...

Advantages of artificial plant cloning - ️️Can grow plants which have low levels of fertility, large number of plants with a known genetic code produced rapidly, can grow rare or endangered plant species, can produce large numbers of seedless plants, disease free plants because meristem is used Advantages of entrapment in matrix - ️️Widely applicable Advantages of membrane entrapment - ️️Relatively simple, small effect on enzyme activity, widely applicable Advantages of surface im...

are microorganisms the only organisms used in biotechnology? - ️️other organisms such as goats and cows are also used in biotechnology for example genetically modified goats produce spider silk in their milk and cows have been genetically modified to produce human antibodies describe the nature of the offspring produced by embryo splitting - ️️although the offspring will all be clones of one another the offspring which develop will depend on the egg and sperm that fuse during fertilis...

Advantages for elm trees to produce clones. - ️️Desirable genetic characteristics are always passed on. Plants may be produce all times of the year. Sterile plants can reproduce. Define biotechnology. - ️️The industrial use of living organisms to produce food and drugs. eg, Bread using yeast. Define reproductive cloning. - ️️It is used to make a complete organism that's genetically identical to another organism Describe how a fermentation vat has been adapted to make conditio...
